Ok I will tie those grounds in before I run it tomorrow and we will see how it does. Hopefully that will stop the color flicker LOL
Your steppers are set 32% higher than ours. You might want to take a look at why you are not homing right. That is a lot, you probably need a fan at that rate. How hot are your steppers??

3.7.10 tested good.

Granted, I use another board, but I have had the same happen to me once before where it drove full speed into X max. So it does happen.

What steppers are you using?
I was having problems homing without significantly more current while using some LDO hotrod 3d printer steppers and it turned out that they had very low impedance motor coils (0.7 ohm for LDO vs 1.8 ohm for V1E). This meant that they could be driven very quickly, but needed a ton of current to have enough torque to drive a CNC router (~2.2A to avoid skipping steps).

I’m using the same steppers he is. The ones from the V1 store. But my X beam weighs significantly more than his lol. Then again he put 20 lbs on his and had no issue so i probably have something wrong somewhere
Typically, it has to do with the screws. Lube, screw, some sort of alignment issue. It has to be pretty bad to have issues. You should easily be able to twist them by hand on the coupler, if they are not, there is an issue. Measure the top spacing at the top of travel and the bottom to see if it moves.
They have a good coating of superlube and i can turn them easily by hand. The only one to have problems was Z1 which is the control board/X+ side. and the only time it had problems was when the Core was on that side. It was when I was trying to level the beam and have to keep homing. I’m sure I
just went too far on the power.
They barely register on the stick on temp gauges I got from you. And very cool to the touch. I will take a pic later today when I get to run it some. Too pretty outside so had to get some painting done while I can…

Yes it is. 3 6’ tall ones and 8 3’ tall ones. So ready to be done making them LOL

It was the hands that gave it away. They look great and I like how you use CNC to create new things

Thank you. That’s what I enjoy the most about having them.

Ok @vicious1 i just brought a ground wire from the negative side of the 12v power supply for the LEDs and tied it into the negative side on the jackpot. The ESP32 already shares a ground with the jackpot since it gets 5v and ground from there to run. The only other thing I’m wondering is should I tie the ground from the RA485 wiring to the jackpot ground. That ground wire is terminated at the house ground on the other end along with my vac hose.

Not 100% sure about that. Those VFD’s can kick out some weird stuff.
Try a regular router and the LED fix to eliminate the VFD as a possible issue. If nothing goes wrong you know it is the VFD, then we can try some things. Currently, you have too many variables.

Man that’s a LOT of work to change over to regular router with how I have everything set up. I just started it up for the first time today (without that last ground, didn’t want to hook that up till you said. It all went smooth as can be. I’m going to run it and see what happens. Last night was the first time it ever did anything weird during a job. It was always just when jogging before. But it stayed until i power cycled it. If it does anything weird ill report back what it says in the terminal. If it keeps acting up I will change out the router to this new shiny Kobalt I have and see what that changes.

I did find that my shielded cable for the spindle wasn’t hooked to ground. That’s fixed. Setting up Estlcam now to make some cuts so we will see how it goes.
One thing I don’t understand is how can it be the VFDs/Spindles fault when none of that was running for all the other problems? Just this once during the cut it messed up but everything else has been during a jog with the spindle off. Not trying to argue with you just trying to understand

Too many variables. I just take guesses based on how many times that has previously been an issue for someone.

Well I just pulled the RS485 Board and its running good. Dark but running good so far. Went to probe and the z motors were running different speeds. Some weird stuff. That really sucks though cause I really liked having that. One thing I might try is some shielded twisted pair. All I had on hand is the shielded wire I bought from you so I ran that. Going to amazon some shielded ethernet and see what happens. I guess it communicating even when the spindle isn’t running was causing problems

Maybe we need to swap the esp32…
